Title: Improvements in or relating to the preparation of purified alcohol from worts
IPC: B01D3/00
Filed: 1935-12-03
Abstract: <PICT:0455947/III/1> The production of pure alcohol from worts according to the process described in Specification 347,122 wherein the tail products are made to behave as head products since they form azeotropic mixtures with water in the worts and are removed with the true head products by subjecting the wort to slight evaporation in a column 3 is improved by subjecting these vapours to an exhaustion treatment in a purifier 9 so as entirely to separate the tail products which are only slightly water soluble, together with the head products and returning the purified wort to the column 3.  The purifier is only slightly heated at its base; the insoluble impurities may be decanted from its lower plates at 11; alcohol vapour from its upper plates is returned to column 3 through pipe 13; and the head products or volatile impurities pass to a condenser 14. Not more than 10 per cent by volume of the wort is evaporated.  In a modification, the alcohol vapour withdrawn from the purifier through pipe 13 is submitted to a supplementary purification in a small auxiliary column to remove products of medium volatility.  The purified wort is then exhausted as usual in the column 4, the alcohol vapours being finally rectified in the column 19.  The rectification may be replaced by other dehydrating means.

Title: Improvements in high-pressure fluid seals
IPC: F16J15/32
Filed: 1957-10-29
Abstract: 834,352. Piston and stuffing-box packings. GENERAL MOTORS CORPORATION, and GARLOCK PACKING CO. Oct. 29, 1957 [Nov. 1, 1956], No. 33777/57. Classes 122 (1) and 122 (5). A packing for sealing the annular space 10, Fig. 1, between two relatively slidable or rotatable members 12, 14 against fluid pressure comprises an L-shaped ring 16 of polytetrafluoroethylene or other hard low-friction material which bears with its radial wall 36 against an abutment member 26 and the free edge 52 of its cylindrical flange 40 against the cylindrical surface 48 of the member 14, and a ring 18 of relatively soft rubber which is disposed between the flange 40 and cylindrical surface of the member 12 and has a substantial portion extending beyond the flange into engagement with a second abutment 22; when set into this position, the ring 18 is substantially underformed but fluid pressure upon the outer cylindrical surface of the extending portion of the ring results in the radial wall 36 being urged against the abutment 26 and the free edge 52 of the flange 50 being pressed against the surface 48. The assembly is maintained in position by a split-ring 30 which is sprung into a groove 32 in the member 14. The abutment member 26 contacts the inner surface 48 of the member 10 to relieve the ring 16 of bearing wear, but the other abutment member 22 has a circumferential clearance to admit pressure fluid to the outer cylindrical surface of the ring 18. The initial assembled length of the elements 22, 18, 16, 26 and a locking ring 28 is slightly in excess of the length between a shoulder 24 and the inner edge of the groove 32 so that end pressure is applied before inserting the ring 30 into the groove 32. In the modification shown in Fig. 2 the rubber ring 62 is pressed into contact with the axial limbs of a U-shaped ring 60 so that the free edges 94, 96 of the latter are forced into sealing engagement with the adjacent cylindrical surfaces of the inner and outer relatively movable members 64, 66, one abutment member being provided by a flange formed integral with the outer member 66 whilst a floating ring 88 forms the other abutment member; the assembly is retained, under axial pressure, by a split-ring 90 inserted in a groove in the outer member 66. Fluid pressure is admitted to the inner and outer exposed surfaces of the ring 62 through the clearances between the inner and outer diameters of the ring 88 and the cylindrical surfaces of the inner and outer elements 64, 66.

Abstract: 752,188. Eddy-current apparatus. COMPAGNIE TELMA. Nov. 22, 1954 [Nov. 25, 1953], No. 33790/54. Class 35. An eddy current brake &c. comprises two rotating spaced apart discs 1, 2 keyed on a shaft 7 and a stationary field structure located between the two discs and includes a number of electromagnets forming a circular row around the shaft, the electromagnet cores 34 being iron bars supported by two parallel plates 32a, 32b positioned perpendicularly to the shaft. The cores 34 have a cross section in the shape of an isosceles triangle with curved sides and rounded apexes as in Fig. 2 and their ends are reduced so as to engage in holes 33a, 33b provided in the fixed plates 32a, 32b respectively. The shape of the cores 34 facilitates the flow of air stream passing along and across them, the air stream is partly discharged via holes 38 in the discs 1, 2 and partly via holes 35a, 35b in the plates 32a, 32b respectively. Fig. 4 shows an arrangement whereby the discs 1, 2 are slidable axially. The hub 5 of each of the discs 1, 2 is splined on the shaft 7 so that it can slide between two limit positions constituted by the abutment of a sleeve 52 against a ring 51a and the abutment of the hub 5 against the coupling 53. Each hub 5 is urged outwardly by a spring 56 so that when the brake coils are not energized the rotor discs 1, 2 are held away from the field structure.

Title: A radio control apparatus for electrically operated toys
IPC: A63H30/04
Filed: 1955-11-25
Abstract: 791,067. Remotely-controlled toys. SAITO, H. Nov. 25, 1955 [April 30, 1955], No. 33822/55. Class 132(3) [Also in Groups XXXVII and XL(c)] A radio-controlled toy car is provided with a coherer receiver and the coherer striking device also operates a switch controlling the driving motor. The dipole aerial 6, 6, Fig. 4, is connected to a coherer 7 which is in the circuit of a meter relay 10 controlling an auxiliary motor 11, which drives a centrifugal device 19. The latter is provided with a striker for the coherer 7 and also operates a switch 12 in the circuit of the driving motor 2. The switch 12 is of the type in which alternate operations open and close a circuit so that the motor may be switched on or off by alternate radio pulses. In the mechanism described, the auxiliary motor 11, Fig. 6, rotates a disc 17 carrying a striker 30 which engages a loop 29 attached to a platform 26 carrying the coherer 7, the platform being carried by springs 27 from a frame 28. Rotation of the motor causes the centrifugal device 19 to advance the disc 17 and striker 30 axially to the operative position. At the same time a member 21 carrying the pivoted, spring-controlled operating member 23 advances to engage the switch member 12. The operating mechanism is retracted by a spring 25 when the coherer is de-cohered and the motor 11 stops.

Title: Improvements relating to electric striking clocks
IPC: G04C21/10
Filed: 1946-11-14
Abstract: 618,938. Electric clocks. STUART, J. F. W., and NORTON, F. D. Nov. 14, 1946, No. 33832. [Class 139] An electric clock having striking or alarm mechanism comprises a part adapted to be displaced at a certain time or at certain times and in such displacement t o move temporarily a pin out of a hole in a disc having peripheral teeth which can oscillate a striking hammer, the said disc when freed being turned by a continuously moving member, to which it is clutched when the pin is allowed, by the termination of the displacement of the part before referred to, to engage the side or face of the disc and apply lateral pressure thereto, the turning of the disc by the clutch resulting in oscillation of the hammer until the pin again enters a hole in the disc, when the clutch is disengaged and the disc held against movement. A lever u Fig. 1, is rocked every hour bv a tooth of a ratchet wheel v and through a lever a moves an arm o against the pressure of a spring p to retract the pin n from one of the holes 2 in a disc f. Fig. 4, wbereupon the pin n is pressed by the spring p against the side of the disc f forcing the clutch members y, k into engagement so that the drive from a continuously rotating wheel h, Fig. 2, is transmitted to the disc f. The teeth 3 of the disc f engage a pallet e and cause the hammer b to oscillate until the pin n enters the next hole 2 in the disc f. The disc f has twelve holes 2 and has groups of teeth 3 between each hole, the number of teeth in each group corresponding to the hour so giving the correct number of oscillations to the hammer b. The ratchet wheel v has one tooth longer than the other eleven so that before the twelfth hour the pin n, through the levers v and q, is given a big enough movement to clear a projection 4, Fig. 4, on the disc f, thus synchronizing the number of hammer blows with the hour. If the disc f is toothed round its whole periphery and provided with only one hole 2. the position of which can be set, the device will operate as an alarm clock.

Title: Improvements in ticket punches.
Inventor: ERNEST WEBER GUSTAVUS
IPC: G07B11/05
Filed: 1922-12-12
Abstract: 212,632. Weber, G. E. Dec. 12, 1922. Ticket punches.-Relates to means for actuating the counting apparatus. A thumb-lever 24 pivoted at 2 to a back plate 1 engages a recess in and actuates a punch slide 8 against the action of a spring 6. The slide 8 is guided between ribs 9, and by a stud 5 on the back plate, and has mounted upon it a punch 19 in which slides a ticket feeler 12. A spring actuated locking pawl 11 pivoted at 21 to the slide is arranged to engage a recess 10 in the back plate until released by the feeler 12 when the latter contacts with a ticket inserted in the slot 18 in the stationary part 16. On release of the pawl 11 the punch may slide freely. The counter 32 is adapted to be actuated on the return stroke of the slide 8. An arm 34 in the counter spindle 33 is engaged by a pin 35 on the slide, and a light spring 36 draws the arm back to register an actuation when the slide returns to normal position. Adjustment of the pin 35 is effected by bending it. The hammer 7 of the bell 4 is capable of universal movement, and consists of a piece of coil spring or the equivalent secured to the stud 5. A pin 31 on the end is engaged by a finger 30 on the lever 24 when the latter is actuated, but on the return of the lever the pin rides over a chamfer on the end. The front cover, Fig. 4, is cast in one piece with the exception of the lid for the clippings box, and is secured to the back plate 1 by screws. The plate 45 has a stud entering a hole 46 in the cover, and is secured by a spring plunger 47 entering a catch 48 rendered tamperproof by a s'ip-in seal card. A flanged ear 49 is arranged to cover the punch lever pivot 2.

Title: Infra-red radiation modulator
IPC: G02F1/015
Filed: 1969-07-04
Abstract: 1,274,703. Modulating light. THOMSONC.S.F. 4 July, 1969 [5 July, 1968], No. 33939/69. Heading H4F. [Also in Division H1] A light intensity modulator, particularly useful in the infra-red range, comprises a doped semi-conductor substrate 3, e.g. Ge, Te, A1Sb, AsGa, GaP x As 1-x , InSb, InAs, an insulating layer 2, e.g. a metal oxide, and a conductive layer 10, together with low reflectance layers 5, 6, so that application of a modulating voltage 4 between the layer 10 and the substrate 3 varies the concentration of free carriers in the substrate and this varies the absorption of light passing therethrough. The layer 10 may be transparent to the radiation e.g. of N-type germanium, to permit transmission of the light as shown, or may be metallic to reflect radiation back through the substrate, Fig. 3 (not shown). A modulator of the first type i.e. transmissive, may be placed with a laser cavity between the active body e.g. a cell of CO 2 , and one of the terminal mirrors to modulate the production of light thereby, while the reflective modulator of Fig. 3 may be used similarly in lieu of one of the terminal mirrors of the laser cavity. In other embodiments, a further oxide and conducting layer are deposited on the opposite face of the substrate 3 giving a symmetrical construction, both conducting layers being biased in the same sense relative to the substrate. In Fig. 4 (not shown) light enters and leaves the semi-conductor via low reflectance coatings, and is repeatedly reflected from the two metal electrodes during its passage. In Fig. 5, (not shown), the metallic layers are semi-reflective so that the modulator operates in the manner of a Perot-Fabry cavity.

Title: Respiratory Apparatus
IPC: A61M16/00
Filed: 1967-07-24
Abstract: 1,175,714. Respiratory apparatus. O. H. DRAGER [trading as DRAGERWERK, HEINR & BERNH. DRAGER]. 24 July, 1967 [22 July, 1966], No. 33979/67. Heading A5T. Respiratory apparatus of the kind including a breathing bag 4 in a closed chamber 5 in which positive and negative pressures are alternately produced, for inducing inhalation and exhalation respectively, of the patient, comprises an adjustable control device 7 including a valve 8 which shuts off the flow of gas from the chamber 5 when the negative pressure therein reaches a predetermined value which is adjusted by adjustment of the control device. The breathing bag is connected to a respiratory circuit 2 which includes a carbon dioxide absorber 2c inhalation and exhalation valves 2a, 2b and an anaesthetic supply conduit 1. When a changeover valve 17 actuated by a diaphragm 14 in response to pressure in a chamber 13 of the control device closes a vent 10a, gas is supplied by an injector 10 to the chamber 5 for the inhalation phase via a conduit 6 and the valve 8 comprising a cup 21 and an adjustably spring loaded diaphragm 18 which is exposed on one side to atmosphere and on the other to the pressure in the chamber 5. Simultaneously pressure builds up in the chamber 13. At a predetermined positive pressure in the chambers 5, 13, the valve 17 opens the vent 10a so that gas from the injector 10 passes to atmosphere and entrains gas from the chambers 5, 13 for the exhalation phase. At a pressure in the chamber 5 determined by the spring-loading of the diaphragm 18, the valve 8 closes shutting off the chamber 5 from the control device so that there is no further drop in pressure in the chamber 5. Further pressure reduction in the chamber 13 operates the valve 17 to close the vent 10a so that gas is again supplied to the chamber 5 for the next inhalation phase.

Filed: 1937-12-08
Abstract: 506,832. Hydrocarbons. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Dec. 8, 1937, No. 33994. Drawings to Specification. [Class 2 (iii)] Ethylene is obtained by cracking saturated hydrocarbons having more than 2 carbon atoms, removing acetylenic and normally liquid compounds, treating the remaining gases with ammoniacal cuprous salt solution to separate olefines which are expelled and pressure distilled to recover ethylene, the higher olefines together with gases unabsorbed by the cuprous salt being passed at elevated temperature over a hydrogenating catalyst, and the hydrogenated gas, after removal of methane, being again cracked, in the same or a separate cracking zone or partly in each, to form ethylene. The initial hydrocarbons may be gaseous homologues of ethane, e.g. propane, or paraffinic or naphthenic liquids, e.g. petroleums, oilsobtained by destructive hydrogenation or from carbon monoxide and hydrogen preferably after hydrogenation. The cracked products may be led over chromium oxide and nickel at temperatures up to 300‹ C., as described in Specification 359,421, whereby acetylenic compounds are hydrogenated. The gases, after separation of liquids, are treated with the cuprous salt solution at pressures up to 50 atmos. By release of pressure; if desired in stages, and preferably while heating, the absorbed olefines are expelled, and may be washed with water to recover ammonia for re-use. After separating ethylene, the remaining gas or the propylene separated therefrom is led with unabsorbed gases consisting of hydrogen and saturated liquid products over metals of Groups 6 to 8 or their compounds, for example, at 100-300‹ C. and elevated pressure. Methane homologues are separated from the hydrogenated gas as by oil washing or distillation, and returned to the cracking. In addition to ethylene, other hydrocarbons may be isolated, e.g. propylene or butylenes or from the liquid cracking products, benzene. Examples described the treatment of the products of cracking propane at 800-840‹ C., and of cracking at about 770- 800‹ C. an oil obtained by reacting carbon monoxide and hydrogen and hydrogenating the product boiling at 200-350‹ C. using a nickelalumina catalyst at 150‹ C. and 180 atmos.
